A:Answer We definitely understand your concern with the chemical, plastic or rubber smells associated with new products and especially in your case where they can be bothersome to an asthmatic child. However, the intensity of the smells or how long they will take to dissipate will vary from one person to the next because environmental conditions that affect that will vary. How you use the LG - 24" Tall Tub Built-In Dishwasher - Stainless-Steel, Model # LDF7774ST will also determine what the intensity of the smells will be like and how long it takes to fade because water temperatures will vary. As a suggestion, if you are able to visit a Best Buy that has this model on display, being familiar with what intensity of smell would be likely to bother your child, you may want to look it over although that by itself does not guarantee that every unit will be the same, but at least will give you some idea. The intensity of the smells and how long they take to fade is something that cannot be duplicated and you may find that one unit smells a little stronger than another or that the smell from one unit takes longer to fade compared to another. Regrettably, there's just no way of predicting this...^IFV
